DOWNLINK PACKET SCHEDULING IN LTE-ADVANCED HETEROGENEOUS NETWORKS

In order to increase the system capacity in next generation wireless networks, optimizing packet scheduling and resource allocation can be an approach. In the context of the existence of multiple Component Carriers in LTE-Advanced, it becomes a complex optimization problem. This paper presents a scheduling algorithm, designed for use in an LTE-Advanced system. It is formulated as a convex optimization problem and is compared to traditional algorithms such as Round Robin and Proportional Fair. Results show that in some situations it provides better performances than the previous algorithms.
